Application filed May 15, 1909. Serial No. 496,816.

To all whom it may concern:

Be it known that we, HARRY H. ARM- STRONG, resident of Oakmont, CHARLES H. CURRY, resident of Pittsburg, .and FRED- ERICK F. HARROLD, a resident of Homestead, all of the county of Allegheny and .State of Pennsylvania, have invented anew and useful Improvement in Metal Boxes; and we do hereby declare the followingl to be a full, clear, and exact description t ereof.

Our invention relates to metal boxes for the transportation of beer, milk, or like bottles.

The object of the invention is to provide with compartments formed therein to receive the bottles, the parts being so combined as to give lightness with great rigidity and strength so as to withstand the severe usage to which such boxes are subjected in handling.

To these ends our invention comprises, the novel features hereinafter set forth and claimed.

In the drawings Figure 1 is a side elevation partly broken away of our improved box; Fig. 2 is an end view partly broken away; Fig. 3 is a section taken on the line 33, Fig. 1; Fig. 4 is a section on the line Fig. 3; Fig. 5 is a section on the line 55 Fig. 2; Fig. 6 is a modified form of the manner of supporting the supporting bars; Fig. 7 is an enlarged section on the line 7-7 Fig. 8; Fig. 8 is a plan view of a portion of the-box; Fig. 9 is a plan view of a modification; and Fig. 10 is a detail of the manner of securing the partitions.

In the drawing the numeral 2 designates the box which is formed of'the sides and ends composed of metal of-suitable gage, and ribbed as at 3 to stiffen the sides and ends and add to the rigidity of the box. Surrounding the box at the edges of the bottom thereof is the bar 4 which is rectangular in cross section and said bar is bentat the corners to form rounded cor ers. The metal, at oradjacent to the lower dges of the sides and ends is bent around the bar 4, the metal as indicated in Fig. 1 being bent outwardly, as at 5, to form the shoulder 6 and is then bent down around the bar and up on the inside thereof, as at 7 Around the upper edge of the box is the angle 8 with which the metal at the upper portions ofthe sides and ends is adapted at 11, and said .wires form posed of the metal sheet bent to engage, said metal being bent over and around and under the angle, as indicated at 9. Resting on the inwardly projectin flange of the angle bar 8 at each corner 0 the box are the angular i'eces of wire, or other suitable material 1 6 which are cov'- ered by the metal of the sides and ends of the box and are held securely in 'place there by. These wires taper off at their ends, as the stacking ridges so that when the boxes are placed one upon the other they can be supported in the manner indicated in Fig. 1.

The longitudinal supporting bars 12 are formed of metal bent to inclose the wire beading 13 at the bottom thereof and one side of said bar is extended beyond the other, as indicated at 14. The bars 12 are further provided at intervals with the open ings 15. The bars 12 are supported at their ends on the bar 1 and the ends of said bars 12 are flattened out, as at 16, so as to rest evenly on the bar 4. The side portions of the bar 4 at their ends project through openings 17 in the end walls of the box and said projecting ends are then bent back, as indicated at 18, to secure the supporting bars 12 rigidly in position. The bottom crossbars 19 extend through the openings 15 in the supporting bars 12 and said cross-bars are preferably T-shaped in form, being comin the T-form with an additional strengthening member 20 inclosing the cross-arm of the T, thereby giving greater strength and rigidity and making 1t dirt proof. The T-bar 19 is cut away at intervals to form the notches 21 and when the cross-bars 19 are .brou ht into engagement with the supportin are 12 said cross-bars are inserted in the openin 15, said openings being of suificient to receive the entire height of the T-bar. When the notches 21 come into coincidence with the beadin 13 on the. supporting bars 12 the T-bar is l wered so that the notches 21 may engage said beading and extend down on both sides thereof to partially inclose said beadin as indicated in Fi 3, and the lower edges of said T-bars are ush or substantially so withthe lower ed of said supportin' bars. This makes the boxes ride easier in t e traveling conveyers in the breweries with less bumping and jolting.

In order to hold the cross-bars 19 down in I position within the openings 15 so that the notches will always engage the beading 13 of the supporting bars the extended portion 14 is provided on one of the sides of the supportin bars 12 so that when the T-bar has been inserted through the openings in the supporting bars, as indicated, the extended portion 14 is bent down to engage or come close to the upper face of the T-bars and so prevent their rising. In this mannerthe T-bars are locked securely in position against vertical movement and by having the notches 21 in said T-bars engaging the beading 13 of the supporting bars the T-bars are also held against any longitudinal movement as well as vertical movement. The ends of the cross-bars 19 project through openings 22 in the side walls and the projecting metal is bent over, as at 23, in order to secure the cross-bars to the side walls of the box.v

The box is provided with compartments to receive the bottles and these compartments are formed by the partitions 24 and 25. The partitions 25 extend cross-wise of the box and are provided with slots 26. The metal at the upper and lower edges of the artitions 25 is bent'around the wires 27 to i orm a beading at the upper and lower edges of the partitions 25. The beading 27 at the lower edges of the partitions 25 has notches 27 a which engage notches 28 in the supporting bars 12 While edge of the partitions 25 take into notches 29 in the partitions 24. In this manner the partitions 25 are held at. their upper and lower edges to prevent lateral .movement. The partitions 25 have their upper beading projecting through openings 30 in the side walls of the box and the metal is then pressed to form a rivet head to secure the partitions 25 to the side walls. In assembling the partitions 24 and 25 the partitions 24 are inserted within the slots 26 of the partitions 25 and, the openings 31 in the end walls to receive the projecting upper beading 32 of the partitions 24 are made at such a height that when the partitions 24 have been'-inserted in the slots 26, said partitions may beraised so as to have their notches engage the beading 27 at the upper edges of the partitions 25. When the partitions 24 have been raised to this position their upper beading'32 will be in alinement with the openings 31 and can be then passed through said openings and the beading riveted to t e ends of the box to in place.

By the above construction it will be observed that the partitions whensecured in place form an interlocking structure in which the cross partitions are held from any lateral movement by engaging the notches in the'partitions 24 as wel as by their ensecure the partitions 24 'gagement with the upper edges of the supthe beading at the upper bars bent to engage the upper lower edges thereof eaaocs porting bars 12. The partitions 24 by this same construction are held as against any longitudinal movement, any tendency to lateral movement being cared for by their engagement with the slots in the partitions 25.

. By the above construction all the parts of the box are so united and braced as to provide a structure in which none of the parts can work loose and cause rattling, while at the same time the rigidity obtained is such as will enable the box to withstand the rough treatment to which such boxes are subjected in transportation andhandling.

In Fig. 6 we have illustrated a modified form of the invention in which the metal of the sides and ends at the lower edges thereof in taking around the lower bar 4' is bent to form the recessed portion 35 and the ends of the supporting bars 12 are extended so as" to enter said recess and give a longer support for the supporting bars 12 at the ends thereof. n

In Fig. 9 we have illustrated a modified form of our invention in which the stacking ridges are formed at points intermediate the corners of the box.

What we claim is:

1. A metal box having an open'bottom comprising supporting bars having headings at the lower edges thereof and having enlarged openings therein, bottom bars passing through said openings and having notches engaging said headings, and means for preventing the upward movement of said bot tom bars.

2. A metal box having an open bottom comprising supporting bars having headings at the lower edges thereof and having openings formed therein, bottom bars enterin said openings having notches engaging sai headings, and portions on said supporting bars engaging the upper faces of said bottom bars.

3. A metal box having an open bottom comprising supporting bars having headings at the lower e ges thereof and having openings formed therein, bottom bars entering said openings having notches engaging said headings, and portions on said supporting faces of said bottom bars.

4.
